无法在Android和NDK下使用gdb进行调试,启动Gdb会崩溃App

概述我在尝试使用 Android NDK调试本机代码时遇到问题. 当应用程序正在运行时,我启动了ndk-gdb,结果是gdb失去了与设备的连接,设备上的应用程序崩溃了. 设备(三星Galaxy 10.1)和模拟器都发生了同样的事情. 主机运行的是Mac OS X.应用程序的本机部分由多个.so库组成,使用ndk-build clean构建所有NDK_DEBUG = 1 我已经在下面附加了gdb输出. 我在尝试使用 Android NDK调试本机代码时遇到问题.

当应用程序正在运行时,我启动了ndk-gdb,结果是gdb失去了与设备的连接,设备上的应用程序崩溃了.

设备(三星galaxy 10.1)和模拟器都发生了同样的事情.
主机运行的是Mac OS X.应用程序的本机部分由多个.so库组成,使用ndk-build clean构建所有NDK_DEBUG = 1

我已经在下面附加了gdb输出.

任何帮助将不胜感激.

编辑：问题可能是’cp’命令失败？空的“使用gdb setup init：”行？

解决方法 我遇到了同样的问题.原来问题是我在$PROJECT_DIR / jni文件夹中执行ndk-gdb.向上移动一个级别并从$PROJECT_DIR执行修复了断开连接. 总结
